DisAssemble=filename
tells the compiler to disassemble the code as it is generated and to
send the disassembly to the file you specify. The default value is
nodisassemble. The minimum acceptable abbreviation is disasm.
To send the disassembly to the Shell, use disasm=*.

----
This is an option you pass to SC.

To avoid having the default startup code linked in, simply choose the nolink option for sc.
